My invention relates to improvements in 'cop frames, and more particularly in cop frames provided with automatic means for dofng the cops and placing empty cop tubes into winding position. One of the objects of the improvements is to provide a frame in which, during winding,

inspection of the cops being formed is not interfered with by the dong apparatus. Another object of the improvements is to provide a frame in which the said dofng .and replenishing apparatus is simple in construction and reliable in operation. With these objects in View, my invention consists in mounting the carrier for the empty cop tubes below the winding position, and providing the same withmeans for lifting the same with one of the cop tubes into position for being taken up by the means holding the cop tube in winding position, and providing in addition means operative when the said carrier is away from the winding position for receiving the cops when released from the winding position.v

Other objects of theimprovements will appear from the following description.

For the purpose of explainingthe invention an example embodying the same has been shown "in the accompanying drawings in which the same reference charactershave been used in all the views to indicate corresponding parts.

In said drawings,

Fig. 1 is an elevationpartly in'secton showing a part of the cop framev andthe dofling apparatus, the cuter `end plate of the carrier for the cop tubes being removed,

Fig. 2 is a sectional elevation taken on'the line 2-'2 of Fig. 1,

y On the transverse member'Z and thedown- Wardly directed portion 4 means are mounted for ,Y supporting the cop tubev1 and thecop V8 formed thereon in winding position, Such means arerk'nown in the art andI shall briefly describe the same. They consist `of a spindle `9 and a `counterfpunch I0 carried by a slide block II acted upon by a spring I2 tending ltov shift the counter-punch to the left in Fig. 2 and into engagement with the tube 1. The slideblock" II is engaged by an arm I3v connected with suitable operating mechanism for retracting the same from Vthetube 1 in opposition to the spring I2, for inserting a cop tube 1 or removing the same with the cop formed thereon.,

Belowthe spindle 9 and the kcounter-punch I0 a device adapted to carry a plurality of cop tubes 1 vis mounted which is provided with mechanism for lifting the same with one ofthe tubes into position between the spindlev 9 and the counterpunch I0. As shown, the said carrier consists of two disks I4 and I5 secured by means ofI screws I6 to arotary shaft I1,` and non-rotatableend plates I8 and I9, the end plate I9y being fixed to a tubular bearing member' 20 in which the shaft I1 is rotatable, and the plate I8 being loosely mounted yon the', shaft I1 and held in position relativelyto the plate I9. by means `of a rod 2l and arms22 xedrespectivelygto the plates I8 and I9. The Vdisks I4 and I5 are provided about their circumferences with cut-,out portions 23 in which the, tubes 1 are-supported ynear their ends,

and the plates I8 and I9 are spaced from the l disks I4 and I5 so that they engage the vtubes 1 Fig. 3 is an elevation partly in section viewed from the left in Fig. 2, Y

Fig'. 4 is atop plan view of the doing apparatus, and

Fig. 5 is a detail sectional elevation on an enlarged scale showing the doing apparatus.

The cop frame may have any known or preferred construction, and in the drawings only such parts of the frame have been shown as are necessary for illustrating the cooperation of the doing apparatus with the winding devices.

yIn the iigures I have shown Yan upright I which is cast integral at its top with a transverse member 2 connecting the same to a similar upright. From the transverse member 2 an arm 3 projects to the right in Fig. v2 which is formed at its end with a downwardly directedportion 4. Further, transverse bars 5 and 6 are secured to the upright I. On the said frame members the operative parts are supported.

at their opposite ends, andl they are also formed with inwardly directed flanges 24, thus holding the tubes 1 in position on,` the disksfl4 and I5.

said shaft being adapted to be rotated from the source of power that rotatesthe cop tube when mounted in'winding position.A Near the rod 21 a set screwv 29 is fitted in the transverse bar 6 which is adapted to arrest the bearing member 20 in itsrlowermost position. y

`By the mechanism so far described the carrier comprising the disks I4 and I5 and the plates I8 and I9 is adapted to beelevated'with the uppermost cop tube 1 into position between the spindle 9 and the counter-punch I8 as is shown in Fig. 1 in dotted lines, and to be removed therefrom into thye position shown in Figs. 1, 2 and 3 in full lines, in which the bearing member 28 rests on the screw 29. To permit the plates I8 and I9 to clear the spindle 9 the counter-punch I and the cop 8, they are formed with cut-out portions 38.

To one end of the shaft II a ratchet disk 3| is secured which is engaged by a spring pressed roller 32 carried by an arm 33 pivotally mounted at 28, and between the arms 25 and 33 there is a spring 35 yieldingly holding the roller in engagement with the ratchet disk, the said roller being adapted yieldingly to hold the disks I4 and I5 in position. To the opposite end of the shaft II a hand disk 36 is secured by means of which the disks I4 and I5 may be rotated.

On a pivot bolt 3'I fixed to the transverse member 2 a pawl 38 is mounted which is adapted to engage the ratchet disk 3I whenever the carrier with its disks I4, I5 is lifted, for advancing the disks I4, I5 one step and setting a tube 'I into position for engagement with the spindle 9 and the counter-punch I8. The said pawl 38 is provided with a weighted arm 39 bearing on a lug 40 of the transverse member 2.

On the bearing member 29 a bell-crank lever is pivotally mounted the upwardly directed arm 4I of which provides a support for a tray or gutter 42 extending lengthwise of and above the carrier I4, I5, I8, I9, and to the other arm 43 of the said bell-crank lever a link 44 is connected which is jointed to the transverse bar 5 at 45. The dimensions of the arm 43 and the link 44 and the position of the pivot bolt 45 relatively to the carrier I4, I5, I8, I9 are such that in the lower position of the carrier I4, I5, I8, I9 the tray 42 is vertically below the spindle 9 and the counter-punch I0 so that it receives the cop from the spindle 9 and the counter-punch I8, when the counter-punch is shifted to the right, and when the said carrier I4, I5, I8, I9 is moved upwardly the tray is shifted to the right and into the position shown in Fig. 1 in dotted lines in which the cop previously taken from the spindle 9 and the counter-punch I0 is delivered to a suitable container. By means of the set screw 29 the member 29 is set into the position in which the tray 42 is exactly below the spindle 9 and the counter-punch I0.

The operation of the apparatus is as follows: After a cop 8 has been formed on a cop tube 1 the counter-punch I0 is retracted, whereupon the cop 8 drops into the tray 42. Now the cam 58 is rotated anti-clockwise in Fig. 2, whereby the carrier I4, I5, I8, I9 is lifted. By such upward movement the tray 42 is moved into the position shown in Fig. 1 in dotted lines through the intermediary of the link 44 and the arm 43, and the cop is delivered into the said container. Near the end of the upward movement of the carrier I4, I5, I8, I9 the pawl 38 engages the ratchet disk 3| and turns the disks I4 and I5 one step and into the position in which a tube 'I is below the axis of the spindle 9 and the counter-punch I0. At the end of the upward movement of the carrier the tube 'I is located between the spindle 9 and the counter-punch I8. The upward movement of the plates I8 and I9 is possible by reason of the cut-out portions 30. Now the counterpunch I0 is shifted to the left so as to clamp the said tube 1 between the same and the spindle 9. Upon further movement of the cam 50 the carrier I4, I5, I8, I9 moves downwardly by gravity, and the tray 42 is returned into the position shown in Fig. 1 in dotted lines.

It will be understood that the thread of the cop is cut before the counter-punch I0 is moved to the right. Such mechanism is known in the art and I deem it not necessary to describe the same in detail.

From the foregoing description of the invention it will be understood that no guiding members or clamps or other holding devices are necessary for holding and releasing the empty cop tubes on the disks I4, I5. The uppermost cop tube is freely supported by gravity in the cut-out portions of the said disks, and the other cop tubes are held within the said cut-out portions by means of the plates I8 and I9 and their flanges 24.

By means of the hand disk 36 the disks I4 and I5 may be rotated by hand while the winding is in progress of the thread upon the cop that is in position between spindle 9 and counter-punch III, and thus empty tubes may be placed into the frame I4, I5.

While in describing the invention reference has been made to a particular example embodying the same, I wish it to be understood that my invention is not limited to the construction shown in the drawings, and that various changes may be made in the general arrangement of the frame and the construction of its parts. For example, my invention is not limited to the construction in which the tray 42 is mounted on the bearing member 20. In lieu thereof the pivot of the lever 4I may be separate from the said bearing member and it may be located, for example, laterally of the axis of the disks I4, I5. In this case the lever 4I may be locked by a suitable stop in the position in which the tray is in position for receiving a cop, a spring being provided for holding the lever in engagement with the said stop.

In the figures I have shown only one cop tube and dolng apparatus. But it will be understood that a plurality of cop tubes and dofng mechanisms are provided in the machine. The cam 50 is rotated for operating the dofng mechanism whenever a cop has been completed.

I claim:

. 1. In a cop frame the -combination with means for supporting a cop tube in winding position, of a rotary carrier adapted to sustain around its periphery a plurality of cop tubes, the said carrier being adapted to be moved to and from a position with one of the sustained cop tubes in alignment with said cop-supporting means, and means for rotating said carrier, whereby on successive movements of the carrier successive carrier-borne cop tubes come to alignment with said cop-supporting means.
